Apple’s sleek design innovations often leave their competitors’ offerings looking stale by comparison. Things like a hidden antenna here or a set of perfectly aligned input slots there don’t happen by accident. Apple is known for its attention to detail. As Mashable points out, no detail escapes their scrutiny. Not a one.

A recent revelation shows this meticulousness applies even to the company website, where a tiny chunk of HTML code prevents from a word being interpreted in the wrong way.

The little trick was unearthed in a tweet by developer Dan Leech earlier this week. On its El Capitan page, Apple used a “span” HTML tag around the world “click,” adding some extra space between letters — probably to make sure it doesn’t look like the word “dick”.

It’s a simple trick, and nearly invisible to the untrained eye. But some users replied to Leech’s tweet, posting how the same page would look like without the “span” tag, and it’s immediately obvious why Apple did it.
